    I got an error while trying to send a test email.
    I checked my username, password, host address and port – all are correct.
    Furthermore, no changes were done on the email side – is it an issue with the last update?

    See error details below:

    WordPress: 5.2.6

    Hi,
    Any idea why this happens? appreciate any help you can provide.

    Thx,
    Amir

    Hi @amirmalka12,

    When you get a chance, could you please let me know if you have two-factor authentication enabled for your account? In that case, you might need an App password from Account > Security Settings. If not, there might be some settings SMTP Authentication disabled within your account, you’ll need to enable that option.

    I hope this helps!

    Thank you for your feedback.
    Yes, i do have 2 authentication protection to my email account.
    what should i do to enable STMP to access my email? Should i download a plugin to my website or add the app to my office365 account?

    Thanks,
    Amir

    Hi @amirmalka12,

    Thanks for the confirmation. If your account has two-factor authentication enabled, you’ll need to use App password rather than your general account password. To create an App password, please go to your Account Security Settings and create an app password. This is the password to use in the SMTP password field.

    Thanks!

    Hi @amirmalka12 – We haven’t heard from you in about a week, so I’m going to go ahead and mark this ticket resolved. If you still have questions, though, please feel welcome to continue the conversation.
